To all whom itmag concern:

Be it known that 1, Joan N. HAHN, citizen of the United- States.residing at- Cleveland. in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Machines for"Pasting lasteboard Packages, of which the following is a specification.

My invention relates to a machine for pasting pasteboard packages, andthe invention consists in a machine adapted particularly to makeeffectual the pasting of the flaps or folds of the package after thepaste has been applied and adapted to hold the package within a givenline of travel between opposed surfaces until the paste has sothoroughly set that the flaps will remain closed or sealed and not flyopen after being discharged from the machine.

In making up pasteboard or like packages, parcels or boxes, sayrectangular boxes with flaps or folds adapted to be turned or hentinward over-other folds of the box, it has beenv found necessary to holdthe flap or fold down until the paste became suiticiently set orabsorbed to secure the flap t i I without further assistance. Such flapsusually are bent at the edge of the box and have quite. a considerableoutward spring tendency so that if they are coated with a comparativelysoft paste they will spring open notwithstanding and pull away from thepaste, that is until the paste has become set. Something must,therefore. be done to hold the flaps down after pasting until there issufficient strength dewaloped. in the paste itself to keep them closed.Various makeshifts have been employed from time to time by differentmanufacturers to accomplish this purpose, but so far as my observationand experience go such devices have entailed a great deal of labor andat their best have been exceedingly primitive and unsatisfactory, andwhere a large output of boxes is necessary the devices here-- toforehave been found utterly inadequate.-

I have therefore conceived the invention herein which consists in amachine which is adapted to convey the ,freshly pasted boxes insuccession one after the other with the flaps folded and pressed downwhere they belong and which will hold them down untihthe paste attains'aconsistency or .-adhesiveness which alone will do" the work and noartificial help is further needed. At least three things are essentialto an opera tion of this kind, namely, that the box should be carried bythe machine in such manner that the flaps or folds will be held down bya sutlicient and sustained pressure, much as they would be held by anoutspread hand or other means gently pressed upon the flap: secondly,that the length 0. the machine should be such that having received a boxin a raw state of paste at one end it will care for the box until it isdischarged in a finished state at the other end, and thirdly. suchartificial means as applied heat or blasts of air to the box in transitas may be helpful to its more or less speedy drying. Of course if-thetravel be rather slow or the machine sufficiently long these helps neednot be extended. Much will depend also upon theconsistency of the paste,the nature of the material pasted, and

other conditions attending such work, but in any event the essentials ofthe machine are those which will take the box with its raw pasting atone end and deliver it sufiiciently dried at the other endof the machineto. prevent the flaps from springing loose or breaking away from thepaste.

Referring to the accompanying drawings, Figure 1 is a plan viewof themachine, and Fig. 2 is a side elevation thereof. Figs. 3. 4, 5 and 6 aredetails of different parts more or less in section as hereinafter fullydescribed. The machine thus shown comprises a suitable main frame F ofwhatever length may be deemed best, say twenty feet more or less, andwhich is provided with two endless a )l'OllS B and B running inhorizontal parallel lines over drums D and D or their equivalentat theends of the machine. Said aprons work in connection with rollers R and Rtop and bottom of a channel or passageway for the boxes A, according tothe depth of the boxes. The-said rollers are in series and comparativelynear to each other successively and relatively small and so arranged ordisposed in each series that several of them will be in acting relationsto a given box as it asses through between them. To this end also thelower series of rollers R is set in a suitable frame E fixed to the mainframe as to its elevation and carrying the said drums D in its ends overwhich the apron A passes, the arrangement being such that the said apronrests over the said rollers. The upper rollers R are set in'a frameGadapted to be raised and lowered in respect to the lower frame androllers according to the size of the box and the amount of pressure tobe exerted upon the same. Said upper frame is slidably suspended uponthe main frame from both ends and is controlled as to elevation. bymeans of sprocket chains C, or their equivalent, run over sprocketwheels W arranged upon a shaft S and adapted to be rotated and for thepurpose of winding up or letting out the said chains according as thesaid frame is to be raised or lowered. The said s rocket mechanism iscontrolled from a sha t S by hand wheel 2 thereon and a pinion 3 meshingwith a gear wheel 4 on shaft S and adapted to operate said shaft S andall that it carries thereby. A pawl and ratchet 5 serve to hold anyrotation that may have been given to shaft S by wheel 2. Said chains Cextend to the respective ends of the frame G and when the wheel 2 isrotated the arrangement and connection of the working parts is such thatboth ends of the frame G are raised or lowered uniformly, thus makingthe channel for the boxes uniform throughout its length and providingeven pressure at all points.

ower is applied or supplied from any suitable source, such as a motor Mwhich is belted 01' geared as at M to a line of mechanism running towhat may be termed the rear drums D and D of the machine, a shaft 6having bevel gears 7 meshing with bevel gears 8 on the said drum shaftsand applying positive driving power thereto.

'This also enables me to cause the machine or said aprons to travel atany desired speed, slower or faster, and move the boxes A along throughthe machine from end to end with the effect that the paste is set whenthey are discharged from the machine.

Power is applied to the drive shaft S from the motor through a shaft 10having a pinion 11 at one end and a worm 12 at the other end engaging agear wheel 13 on shaft S which in turn operates shaft 6. The foregoingor any other or equivalent power transmitting means may be employed withthe understanding that it is such as to actuate said aprons uniformly asto speed and in the same direction.

Either plain surfaced aprons A and A or their equivalent adapted tocarry the boxes and pass uniformly on the folds thereof may be adaptedand be within the spirit of my invention.

Bevel gears 7 and 8 for upper drum D are mounted in a bracket 15 securedto movable frame G (see Fig. 6), and a slidablc key connection 16 isused between gears 7 and shaft 6 to permit up and down movements offrame G.

-W'hat I claim is A machine as described for pastingand drying boxeshaving two endless aprons op positely disposed parallel to each otherand 1 two frames having rolls at their ends over \VhlCll said apronstravel, a series of rollers for each apron having hearings in saidframes and exposed above theopposed surfaces thereof, means to spacesald frames 'apart at varying distances according to the sizes of theboxes to be pasted comprising flexible adjustable 'suspensory supportsfor the upper of said frames extending from the middle of the machine toboth ends of said frame, and means to jointlyoperate said aprons at thesame rate of speed and in the same direction, the said aprons being.stretched over their respective frames and running in contact with saidrollers, the lower of said frames being fixed'in the main frame.

In testimonv whereof I ailix in presence of two witnesses J OHN' N.HAHN.
